A Methodology for Classification and Evaluation of IoT Brokers

Abstract: Since the term Internet of Things (IoT) was coined by Kevin Ashton on 1999, a bundle of middleware platforms has been developed to cope with important challenges such as the integration of different technologies. Is in this context of heterogeneous technologies that IoT message brokers become key elements for the proper function of smart systems and wireless sensor networks (WSN) infrastructures. This article proposes a methodology for classification and evaluation of brokers by using qualitative analysis, so to help in the selection of the more suitable brokers according to the given scenario and needs. The methodology uses the quality reference model described on the ISO/IEC 25010 normative from the SQuaRE set of standards published by the ISO/IEC conjunction. In the implementation case we developed the proposal with 9 different open source brokers so to validate the applicability and feasibility of our methodology.
